Study site location & description http://www.desire-his.eu/index.php/en/secano-interior-chile/150-secano-interior-chile-study-site-description http://www.desire-his.eu/index.php/en/secano-interior-chile/150-secano-interior-chile-study-site-description The Secano Interior study site is located west of the city of Cauquenes, central Chile.

Erosion is the main cause of degradation of the soils in Chile. Due to the topographic conformation of the country, with two large mountain ranges along the country, and the rain intensity and distribution, which is highly concentrated in winter, water erosion is the most important form of soil degradation. With a territorial area of 75.49 M ha, 46% (34.491 M has) are affected by erosion of different degrees; 7% of soils presents a severe erosion, while 27% are highly eroded, 44% moderately degraded and 22% are in state of light erosion degree (IREN, 1979). In the Mediterranean climate area of Central Chile, in particular the unirrigated area ("secano interior") of central Chile (30° - 37°S), soil degradation and desertification are actually the main environmental problems. Most of this 2 million ha is occupied by a traditional agricultural system that combines livestock activities with the production of cereals. As a result of the prevailing land use systems, about two thirds of "secano interior" soils are badly eroded and soil organic matter and microbial biomass are very low in many places (Ovalle, et al., 1990). At macro regional level, the erosion has provoked environmental imbalances, like siltation of rivers and ports, and serious problems of floods as much as rural level as in the cities. The studies will contribute to the rehabilitation and development of one of the most economically depressed areas of the country, with high levels of rural poverty and degradation of the natural resources. In particular, it is expected that appropriate technologies for the sustainable management of these fragile soils will be transfer to farmers and associations, institutions and technical staff involve in soil conservation and local governments. A concrete contribution is expected in the area of the development of production systems through the incorporation of cover crops and agroforestry systems with multi purpose trees and pastures, and the development of new crop systems and crop rotations with incorporation no tillage of cultivation systems. Besides, studying how to improve agronomic practices would allow to increase soil fertility and the productive potential of this extensive area of the country.

Stakeholders and their sustainability goals http://www.desire-his.eu/index.php/en/secano-interior-chile/760-stakeholders-and-their-sustainability-goals http://www.desire-his.eu/index.php/en/secano-interior-chile/760-stakeholders-and-their-sustainability-goals The area and people
On this site the majority of the farmers are small farmers.

 

Added value of DESIRE for stakeholders
The local actors hope that this project will influence the decision makers to finance the implementation of the solutions. The INIA felt a very strong expectation of the local actors.

 

Study site stakeholder workshops
One day with the local actors; small farmers, big owners, representatives of 4 institutes of research (INIA, IDAP, IRD), representatives of companies and a technician of the municipality. Then two days with the external actors. The INIA was very satisfied with the participation.

 

Limitations for spontaneous implementation of soil and water conservation practices
The solutions are too expensive for these poor populations and absence of a public policy.

 

Stakeholder groups

  • A fundamental and key user institution of the information generated by the project would be the Institute of Agricultural Development (INDAP, http://www.indap.gob.cl). INDAP has for mission to attend technically and to lend credit to the small farmers of Chile. In particular in the Mediterranean region INDAP develop programs for recovery degraded soils, fomenting tools for soil conservation like the construction of simple structures for erosion control at farm level, cover crops and sown pastures, and the plantation of trees with agro-forestry purposes.
  • The Centre of Education and Technology (CET, http://www.corporacioncet.cl) has the mission of help small farmers to increase their life quality improving their technology, agriculture productivity and sustainability of natural resources. The CET has an active role on the articulation of rural organizations with county authorities, research centers and state institutions, in order to have influence on the design of new polices related with rural life.
  • A number of NGOs are available in the secano interior working with small farmers, like Agraria, Grupo de Investigaciones Agrarias (GIA,  http://www.gia.cl) among others.
  • The large majority of the land in the “secano interior” is private, therefore farmers and forest companies will the final users. An active divulgation program will be necessary for the diffusion of new technologies to small, medium and large farmers, as well as forest managements.

 

Sustainability goals

The areas of rainfed agriculture in Mediterranean Central Chile have at least 2 main attributes, which should be preserved and enhanced. First is the livelihood for a significant number of farmers (c. 300.000), who use and generate their incomes from agriculture activities, and contain a valuable cultural and social heritage that the country can not lose. Secondly, being semi-natural areas, where the anthropogenic impact on the environment have been not as overwhelming or devastating as in other areas of more intensive agriculture, these zones have great interest in terms of biodiversity and semi natural landscape.Taking into account both aspects the sustainability goals are to allow rural population to improve their living conditions and to conserve natural and  cultural  patrimonies.

 

Goal 1 Enhancement of the productive potential of the dryland agroecosystems
Goal 2 Rehabilitation and restoration of degraded soils
Goal 3 To decrease and control  soil degradation (erosion and fertility depletion)
Goal 4 To enhance water storage capacity of the soils and watershed
Goal 5 Maintenance of balance between ecological and productive value of the agro-ecosystems
Goal 6 Design, implementation and introduction of technological innovations in the traditional farming systems allowing rural population to improve profitability, productivity and sustainability of agriculture, preserving the environment and cultural and natural patrimony of this vast area of Central Chile

Drivers, policies and laws http://www.desire-his.eu/index.php/en/secano-interior-chile/761-drivers-policies-and-laws- http://www.desire-his.eu/index.php/en/secano-interior-chile/761-drivers-policies-and-laws- The reasons for desertification and land degradation occurring can be environmental (for example due to the climate or soil conditions), economic, due to the actions of people or, most often, due to a combination of factors. The resulting degradation may be temporary or permanent.

 

To help understand this complex picture it can be helpful to think in terms the dominant socio-economic and environmental forces that are driving the process of land degradation. These place pressures on the land which have particular impacts. Human society may have already made responses to those impacts, or may have knowledge about how they could respond. Decisions about which responses to make may also be governed by a range of international, national or local policy regulations and agreements.

 

In the Secano Interior study site, the same stakeholder workshop and questionnaires that were used to identify existing and potential response strategies (»Identifying strategies: Stakeholder workshop 1) also discussed and identified these driving forces; pressures; impacts; and the policy and regulation environment. This information was then used to inform the choice of »Field experiments, the scenarios used in »Simulated biophysical impact of remediation strategies and their financial viability, and context for the study site-specific »Policy brief recommendations.

Evaluating the desertification risk assessment tool with local experimental results http://www.desire-his.eu/index.php/en/secano-interior-chile/913-evaluating-the-desertification-risk-assessment-tool-with-experimental-results http://www.desire-his.eu/index.php/en/secano-interior-chile/913-evaluating-the-desertification-risk-assessment-tool-with-experimental-results Author: Victor Jetten

 

Introduction
In the dry Secano interior in Chile, farmers face problems of soil fertility depletion which affects the sustainability of traditional crop production. Another problem associated with fertility depletion is erosion because of periods in the crop rotation cycle where the soil is bare. Experiments were carried out to introduce crop rotation with legumes to replace wheat mono culture and to solve the problem of soil fertility depletion, while at the same time providing a better soil cover and also improving the soil structure, which improves infiltration.

 

Also the problems of soil erosion and soil degradation are caused by the Mediterranean type of climate (heavy rainfall in winter) and inappropriate land management practices. Experiments were carried out on the experimental farm to decrease surface runoff and soil losses and to improve soil water availability for growing crops.

 

Desertification indices
The desertification risk calculated is water erosion. The calculated risk is moderate (2.52). Introducing a rotation system will presumably increase the soil cover which is an option in the tool. This lowers the risk to low (2.30) while the minimum tillage also results in an even lower risk (2.18) because the ploughing is stopped.

 

 

Conclusions
The desertification risk assessment tool correctly identifies the risk for water erosion in this area and the effect of the mitigation measures.

Authors: Carlos Ovalle, Carlos Ruiz, Alejandra Engler.

 

Overview

 

  • The Mediterranean dryland area is located in the VII and VIII Region of Chile. It covers an area of 800.000 hectares. The average rainfall is 640 mm per year, heavily concentrated in the winter season. The population is around 100.000 and 19.000 families.

 

  • A history of overuse of natural resources (land and water), bad cropping practices and abusive extraction of native plantations have placed high pressure on soil and water conservation.

 

Selection of technologies and approaches

 

 

Final comments

  • Participants agree in concluding that one of the main factors affecting degradation is inappropriate practices.
  • Solutions proposed imply right incentives, education, and participative extension programs.
  • Generating the right technologies still requires more evaluation and research.

November 12th 2009.

Authors: Carlos Ruiz, Alejandra Engler

 

NB This page contains a mixture of English and Spanish content.

 

The workshop methodology was designed and coordinated through Research Theme 3: Potential prevention & mitigation strategies and consisted of three main elements:

  • A participatory approach to guide and lead the workshop participants through a process of multi-criteria evaluation of different options which finally results in decision-making on strategies to be field-tested.
  • The WOCAT database containing locally applied options as well as options from a number of other contexts.
  • 'Facilitator', a Multi Objective Decision Support System (MODSS) software to support the single steps of the evaluation and decision-making process.

Target groups were the same as in the 1st workshop: local stakeholders (land users, representatives of local authorities, local NGOs) and external stakeholders (researchers, development professionals, NGOs, GOs).

 

 

The following strategies were discussed during the workshop.
